Hello folks,

I´m using the natural_neighbor_coordinates_2 function as:

----------------------------------
typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;
typedef CGAL::Delaunay_triangulation_2<Kernel>  Delaunay_triangulation;
typedef Kernel::Point_2 Point;
typedef Kernel::FT Number;
typedef std::pair< Point, Number > Point_coordinate;
typedef boost::numeric::ublas::matrix<Point_coordinate> Point_coordinate_matrix;

Point_coordinate_matrix shape_functions(support_domain_size,support_domain_size);

Point_coordinate_matrix::iterator1 it_row = shape_functions.begin1();
CGAL::Triple <Point_coordinate_matrix::iterator1,Number, bool>
   result = CGAL::natural_neighbor_coordinates_2(support_domain_dt, test_number, it_row);
----------------------------------

The objective here is to put the natural neigbhor coordinates at the current row in the boost matrix.

The VC++ 9.0 compiler generates this error: 
error C2679: binary '=' : no operator found which takes a right-hand operand of type 'std::pair<_Ty1,_Ty2>' (or there is no acceptable conversion)    c:\arquivos de programas\cgal-3.3.1\include\cgal\natural_neighbor_coordinates_2.h    62

Isn´ the matrix row operator a valid output operator?

Thanks,

David Reis
